Class TransferableGraphic

java.lang.Object
  jpicedt.graphic.toolkit.TransferableGraphic

All Implemented Interfaces:

ClipboardOwner, Transferable

public class TransferableGraphic
extends Object
implements Transferable, ClipboardOwner

Wrapper for Element's that can be transfered to/from a Clipboard. Contrary to a BranchElement implementation:

• this object stores a reference to a CLONE of the Element(s) of interest, not to the Element(s) itself (this allow the source Element to be further modified w/o affecting the content of this TransferableGraphic, which is necessary for proper ClipBoard behaviour)
• As a result, Element's added to this TransferableGraphic have no parent, no view,…

Field Summary

static DataFlavor

JPICEDT_DATA_FLAVOR the DataFlavor for Element's

Constructor Summary

TransferableGraphic(Element[] elements, String formatted, PECanvas sourceBoard)
Construct a new TransferableGraphic from a clone of the given elements and the given String containing the formatted representation of the elements (this depends on the ContentType of of the caller).

Method Summary

PECanvas	getSourceBoard()
Object	getTransferData(DataFlavor flavor)
DataFlavor[]	getTransferDataFlavors()
boolean	isDataFlavorSupported(DataFlavor flavor)
void	lostOwnership(Clipboard c, Transferable contents) Notifies this object that it is no longer the owner of the content of the clipboard This implementation does nothing.

Constructor Detail

TransferableGraphic

public TransferableGraphic(Element[] elements,
                           String formatted,
                           PECanvas sourceBoard)

Construct a new TransferableGraphic from a clone of the given elements and the given String containing the formatted representation of the elements (this depends on the ContentType of of the caller).

Parameters:

elements - an array of elements to be set as the content of this Transferable

formatted - the text representation of the given elements (can be null)

sourceBoard - the board from which the elements are copied (can be null)

Since:

jPicEdt 1.3.2

Method Detail

getSourceBoard

public PECanvas getSourceBoard()

setSourceBoard

public void setSourceBoard(PECanvas board)

getTransferData

public Object getTransferData(DataFlavor flavor)

Specified by:

getTransferData in interface Transferable

Parameters:

flavor - the requested flavor for the data

Returns:

An Object which represents the data to be transferred. Current implementation returns an array of elements if flavor is of type JPICEDT_DATA_FLAVOR, or a string representation of the elements (as given in the constructor) is flavor is of type DataFlavor.stringFlavor.

Since:

jPicEdt 1.3.2

getTransferDataFlavors

public DataFlavor[] getTransferDataFlavors()

Specified by:

getTransferDataFlavors in interface Transferable

Returns:

An array of DataFlavor objects indicating the flavors the data can be provided in.

Since:

jPicEdt 1.3.2

isDataFlavorSupported

public boolean isDataFlavorSupported(DataFlavor flavor)

Specified by:

isDataFlavorSupported in interface Transferable

Returns:

whether or not the specified data flavor is supported for this TransferableGraphic Currently only stringFlavor and javaJVMLocalObjectMimeType are supported.

Since:

jPicEdt 1.3.2

lostOwnership

public void lostOwnership(Clipboard c,
                          Transferable contents)

Notifies this object that it is no longer the owner of the content of the clipboard This implementation does nothing.

Specified by:

lostOwnership in interface ClipboardOwner

Since:
